Ok

Yeah, I stumbled upon this issue on my own today and updated
grml-live templates so they don't use persistent=nofiles any longer
but just "persistent"

Yeah, the wiki page on persistent definitely needs some love!
Would be great if you could help us on improving that.

Thanks for that, this definitely helps:

  blkid -o value -s TYPE /dev/sdb4
  FSTYPE=vfat
  [...]
  mount: mounting aufs on /root/ failed: Numerical argument out of domain

This matches exactly http://bts.grml.org/grml/issue1079 which I
tried to reproduce but couldn't with a recent autobuild ISO.

Could you please try again with persistency using on an ext3
filesystem instead of vfat? Do you have the mkfs.vfat command line
available you used for creating the file system?

It would be very interesting to know whether you can reproduce this
issue with the 2012-01-14 daily ISOs that are supposed to be
available during the next few hours.

nice :)

Thanks, Charles!
